This antenna is a 20 to 25 foot long 6 0 m to 7 6 m off center fed dipole antenna for the 20 m and 40 m bands designed for those who need to conceal an antenna.
Attic dipole plans.
You can a 50 linear loading line in each leg of the dipole without loss.
The better your antenna the more success you will have making contacts.
I got about a 1 8 1 vswr perhaps due to 120vac power wires a few feet away.
Mac af4ps fp 51 note.
Ridgeline ocf dipole layout physically shortened dipoles are practical too for an attic antenna.
You can build a double bazooka with the same results as a linear.
Loft attic antennas for restricted spaces m.

It is small enough to fit inside the attic of many homes.
The attic is hot if you need to be told don t climb your outside tower in the ice storm then you should also appreciate the advice don t build attic antennas in the heat of the summer when the attic is 50c attic work requires the physical skill needed to climb rafters and not fall through the ceiling.
Hung dipole up in the attic using a nail at each end into the wood.
When there is insufficient area to mount a full size dipole.
I hoped to find something that would work on with a 100 watt hf transceiver on all bands from 80m through to 6m.
The infamous attic dipole.
This was installed at a previous qth i will be the first or millionth remember i m from fl to affirm that the antenna is the determining factor for success when it comes to one s station set up.
Dipole and long wire antennas can also be used with mobile outdoor style auto tuners feeding them in an attic space.
Another local uses an hf loop antenna tacked up around the circumference of the ceiling of a second floor bedroom.
